I realise that the majority of people who read this blog know that Tremors was a documentary, but there are still some poor souls who are convinced Val, Earl, Burt and the other Perfectionites were actors.

Never fear! If someone seems confused about Graboids and their ways, just point them in the direction of this rather nifty wildlife film created by Frank Robnik, a student in Germany. Robnik wanted to explain how Graboids survived deep underground and this animation does the job admirably.
